This is my first post on this forum but I have learned a great deal by reading many of the other topics. Thanks for this great website!
Okay, hereís my dilemmaÖ My wife and I purchased a home one year ago and our 1.5 hp submersible well pump has recently started blowing the 15A time-delay fuses. This happened for the first time about 2 months ago and has reoccurred 5 or 6 times since then. I have followed the diagnostic tests in the Franklin Electric AIM manual and determined the amperage draw on the motor is too high (possibly bearing failure?). The Max S.F. amperage for this motor is 11.5 and Iím seeing between 11.8A Ė 12.3A. I had a local pump company come out to verify my diagnosis and they agreed that bearing failure in the motor was likely to blame. The pump/motor also makes a fairly loud humming and vibration when operating. The well still produces great pressure and flow so Iím hoping to be able to just replace the motor and reuse the pump.
The pump company quoted me $800 in labor to remove and reinstall the pump. This seemed very high to me so Iíve decided to tackle the project myself. The pump is set at 84í (4 joints of 1.5Ē galvanized). Iíve thought about replacing the galvanized drop pipe with PVC to allow for easier removal in the future but I hate to throw away the galvanized pipe as it was recently replaced in 2007 by the previous owners. Any suggestions here?
A friend of mine has a boom truck that is capable of lifting 21 feet and I was planning to make a threaded bail type adapter and steel plate for holding the joints above the casing.
I consider myself to be a competent do-it-yourselfer but I must admit Iím a little scared to tackle this pump. The thought of dropping the entire assembly concerns me. Any thoughts, tips, suggestions or encouragement would be greatly appreciated!
